BACKGROUND Field

The present disclosure relates to a technical field of display devices,and more particularly to a display panel of an active matrix organiclight emitting diode (AMOLED), and a display device having the AMOLEDdisplay panel.

Background

With the rapid development of flat panel display technology, comparingAMOLED display devices with conventional liquid crystal display (LCD)devices, the AMOLED display devices include many characteristics ofbeing lighter and thinner, self-luminous, having lower powerconsumption, no backlight source, no visual angle limit, and a betterresponse rate. Thus, the AMOLED display devices have become a mainstreamof next-generation display technology, and are more and more widelyused.

Currently, a gate driver on array (GOA) feature is used to drivecircuits arranged in an AMOLED display panel, for replacing externalconnected integrated circuits (IC). The GOA feature can simplifymanufacturing processes of the AMOLED display panel, and the productcost is reduced, such that integration of the AMOLED display panel isincreased, and the AMOLED display panel tends to be thinner. However, ina small size of a display panel, a GOA circuit is arranged on one sideof the AMOLED display panel and occupies a larger area. The area cannotbe used to display images, and thus, decreases display areas of theimages, such that a visual screen ratio of the AMOLED display panel isreduced, where the visual screen ratio is defined as a ratio between asize of the display panel and a visual region of the display panel.

Therefore, for the display panel in related art, a side area of thedisplay panel occupied by the GOA circuit is increased, therebydecreasing the visual screen ratio of the display panel. A full displayscreen of the display panel cannot be achieved.

First Embodiment

As shown in FIG. 2a and FIG. 2b , an AMOLED display panel of the presentdisclosure includes a substrate 201, a light-emitting device arrayarranged on the substrate 201, a switch unit 205, and a gate drivingunit 206.

The light-emitting device array includes a first light-emitting devicearray 202, a second light-emitting device array 203, and a thirdlight-emitting device array 204. The first light-emitting device array202 is arranged on a side of the third light-emitting device array 204in the first dimensional direction, and the second light-emitting devicearray 203 is arranged on a side of the third light-emitting device array204 in the second dimensional direction.

The third light-emitting device array 204 is arranged in a first regionof the AMOLED display panel. The first light-emitting device array 202and the second light-emitting device array 203 are arranged in thesecond region of the AMOLED display panel.

For example, the gate driving unit 206 is arranged below the first lightemitting device array 202, and the data signal driving unit iscorrespondingly arranged below the second light emitting device array203.

In the first dimensional direction, a size of the light emitting devicein the first light emitting device array 202 is greater than a size ofthe light emitting device in the third light-emitting device array 204.

In the second dimensional direction, a size of the light emitting devicein the second light emitting device array 203 is greater than a size ofthe light emitting device in the third light-emitting device array 204.

For example, the size of the light emitting device in the first lightemitting device array 202 is the same as that of the light emittingdevice in the second light-emitting device array 203.

In one embodiment of the present disclosure, only the size of the lightemitting device near the driving circuit in a display layer is changed,and the size change of the whole display layer 202 is smaller. Thus,size calculation frequency of the light emitting device is reduced, anerror rate is decreased, and the light emitting device is relativelysimple in a manufacturing process. Only two size types of light emittingdevices are arranged in the display layer 202, and the design of themask plate used for preparing the light emitting device is relativelysimplified. Only the size of regions corresponding to the first lightemitting device array 202 and the second light emitting device array 203needs to be changed.

As shown in FIG. 2c , an AMOLED display panel of the present disclosureincludes a substrate 201 and a light-emitting device array arranged onthe substrate 201. In comparison with FIG. 2b , the light emittingdevices of the first light-emitting device array 202 in at least onedimensional direction have different sizes. The light emitting devicesof the second light-emitting device array 203 in at least onedimensional direction have different sizes.

For example, in the first light-emitting device array 202, from a side,that is away from the gate driving unit 206, to another side near thegate driving unit 206, a length of the light emitting devices in thefirst light-emitting device array 202 are increased, along the firstdimensional direction. In the second light-emitting device array 203,from a side, that is away from the data signal driving unit, to anotherside near the data signal driving unit, a length of the light emittingdevices in the second light-emitting device array 203 are increased,along the second dimensional direction.

In the first light-emitting device array 202, from a side, that is awayfrom the gate driving unit 206, to another side near the gate drivingunit 206, an interval number n of the light emitting devices in thefirst light-emitting device array 202 are spaced apart along the firstdimensional direction. In the second light-emitting device array 203,from a side, that is away from the data signal driving unit, to anotherside near the data signal driving unit, an interval number m of thelight emitting devices in the second light-emitting device array 203 arespaced apart along the second dimensional direction.

In the first light-emitting device array 202 along the first dimensionaldirection, an incremental difference y of continuous light emittingdevices is defined as an expression that a width λ of the gate drivingunit 206 is divided by the interval number n of the light emittingdevices. In other words, along an incremental length direction of thefirst light-emitting device array 202, the incremental difference y isdefined as a difference between one light emitting device and anadjacent light emitting device.

Similarly, in the second light-emitting device array 203 along thesecond dimensional direction, an incremental difference y′ of continuouslight emitting devices is defined as an expression that a width x′ ofthe data signal driving unit is divided by the interval number m of thelight emitting devices. In other words, along an incremental lengthdirection of the second light-emitting device array 203, the incrementaldifference y′ is defined as a length difference between a length of onelight emitting device and a length of an adjacent light emitting device.

For example, an area of the first light-emitting device array 202 hasone third of an area of the third light-emitting device array 204. Anarea of the second light-emitting device array 203 has one third of anarea of the third light-emitting device array 204. Thus, a coverage areaof the first light-emitting device array 202 is greater than that of thegate driving unit 206, and a coverage area of the second light-emittingdevice array 203 is greater than that of the data signal driving unit.In one embodiment, a length of the first light-emitting device array 202in the first dimensional direction is increased, and a length of thesecond light-emitting device array 203 in the second dimensionaldirection is increased. Namely, the interval number n or the intervalnumber m of the light-emitting devices is increased, such that theincremental difference y or y′ of the continuous light-emitting devicesare further reduced. In the first or the second dimensional direction, asize difference of the adjacent light-emitting devices is smaller, andthe size difference is changed smoothly, such that the size differencebetween the display image of the corresponding region and the displayimage of the third light-emitting device array 204 is reduced.

In the first light-emitting device array 202 and the secondlight-emitting device array 203 of the first embodiment, size changes ofthe light emitting devices are in a gradually changed transition, suchthat a dislocation between the first light-emitting device array 202 orthe second light-emitting device array 203 connected with other areascan be prevented, thereby improving display quality of images.
